Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485618, here are decompositions:

59 + 2147485559 = 2147485618
71 + 2147485547 = 2147485618
101 + 2147485517 = 2147485618
167 + 2147485451 = 2147485618
197 + 2147485421 = 2147485618
281 + 2147485337 = 2147485618
359 + 2147485259 = 2147485618
521 + 2147485097 = 2147485618

Showing the first eight; more decompositions exist.
